I think, therefore I am.

Fall down seven times, stand up eight.

Don't be afraid to take an unfamiliar path.  Sometimes they're the ones that lead you to the best places.

The bad news is time flies, the good new is that you're the pilot.

There are no bad mistakes in maths, only discoveries.

The greatest mistake we make is living in constant fear that we will make one.

The gift of imperfection - let go of who you think you're supposed to be and embrace who you are.

Hard work - a two way street where you get exactly what you put in.

Failure is NOT your destiny. Failure is the key to success.

Don't expect to be good at maths or understand things straight away. Be patient and persistent. Rome wasn't built in a day, but they worked on it every single day. 

Life is full of opportunities. With every opportunity that is missed, another one is born.

Twenty years from now you will be more disappointed by the things you didn’t do than the things you did do

He who has begun his task is half-way done. Have the courage to begin!

There is no talent here. There is hard work and obsession. You could be anyone if you put in the time.

Do Not Be Afraid To Make Mistakes. Each mistake teaches us something.
